The use of Platelet Rich Plasma (PRP) in cosmetics is getting great results. This scientific research article placed PRP in one section of skin and just placebo (saline) in another section of skin. About a month later they took samples from both sections and examined them under a microscope. The section of skin treated with PRP had a higher level of good collagen. Collagen helps skin keep a fresh, youthful appearance. Dr A.J. Cummings has years of experience using PRP to rejuvenate skin.
